1374484 九、發明說明: 【發明所屬之技術領域】 本發明係有關於一種基材固持設備。特別地,本發明 得’有關於一種包含兩個或更多個可交換位置之基材固持器 之基材固持設備’藉此使得一基材固持器利用通過一離子 束來掃晦一基材,同時多個基材可以在其他固持器上被替 換。1374484 IX. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a substrate holding device. In particular, the present invention is directed to a substrate holding device for a substrate holder comprising two or more exchangeable locations, thereby enabling a substrate holder to sweep a substrate by passing an ion beam At the same time, multiple substrates can be replaced on other holders.

【先前技術】 雖然本發明不受限在離子植入機的領域,此領域係對 應於所構想出的應用且對於本發明瞭解提供了有用的文章 脈絡。因此,以下將敌述離子植入機。[Prior Art] Although the present invention is not limited to the field of ion implanters, this field provides a useful context for the applications contemplated and for the understanding of the present invention. Therefore, the enemy ion implanter will be described below.

離子植入機為公眾所熟知,並且通常符合如下的普遍 設計。一離子源係從前驅物氣體或類似物產生一混合的離 子束。通常僅有特定物種的離子是需要用於植入於基材 中’例如用於植入於半導體晶圓中的特定摻雜質。需要的 離子是利用一質量分析磁鐵(mass-analysing magnet)與 一質量解析狹缝(mass-resolving slit)的組合而從混合的 離子束中選出。因此,包含有幾乎專門需要的離子物種之 離子束係從質量解析狹縫顯露出而被傳送至製程腔室,其 中離子束在製程腔室内係入射至被基材固持器所固持在離 子束路徑的基材上。 通常,離子束的截面輪廓係比欲被植入的基材小。例 如,離子束可以是在一轴向方向小於基材之帶狀束,或在 5 1374484 兩軸向方向笑於基材之點狀束。為了確保離子植入橫越整 個基材,離子束與基材係相對於彼此地移動,從而使離子 束可以掃搖整個基材表面。這是藉由以下方式來實現:(a) 將離子束偏斜以掃瞄橫越基材,其中基材被固持於固定位 置;(b)機械性地移動基材,同時保持離子束路徑為固定; 或(c)將離子束偏斜且移動基材之组合。對於點狀束,相對 運動通常被實施成使得離子束跟隨基材上的一光柵圖案。Ion implanters are well known to the public and generally conform to the general design below. An ion source produces a mixed ion beam from a precursor gas or the like. Typically only ions of a particular species are required for implantation in a substrate, e.g., for implantation into a particular dopant in a semiconductor wafer. The desired ions are selected from the mixed ion beam using a combination of a mass-analysing magnet and a mass-resolving slit. Therefore, the ion beam system containing the ion species of almost exclusively required is exposed from the mass resolving slit and sent to the process chamber, wherein the ion beam is incident in the processing chamber to be held by the substrate holder in the ion beam path. On the substrate. Typically, the cross-sectional profile of the ion beam is smaller than the substrate to be implanted. For example, the ion beam may be a ribbon beam that is smaller than the substrate in an axial direction, or a point beam that is smirked on the substrate in a biaxial direction of 5 1374484. To ensure that the ion implantation crosses the entire substrate, the ion beam and substrate are moved relative to one another such that the ion beam can sweep across the surface of the substrate. This is achieved by (a) deflecting the ion beam to scan across the substrate with the substrate held in a fixed position; (b) mechanically moving the substrate while maintaining the ion beam path Fixed; or (c) deflecting the ion beam and moving the combination of substrates. For a spot beam, the relative motion is typically implemented such that the ion beam follows a grating pattern on the substrate.

我們的美國專利US6,956,223係描述一種上述一般設 計之離子植入機。一單晶圓被固持在可移動的基材固持器 中。雖然可以操控離子束,植入機被操作成使得離子束在 植入期間係依循固定路徑。反之,晶圓固持器係沿著兩正 交軸移動,以使得離子束依循光柵圖案在晶圓上方掃瞄。 上述設計對於連續的晶圓處理是特別適合的,其中操 控裝置必須在欲被植入的新晶圓載入之前將經處理的晶圓 卸載。在每一次植入之間將晶圓載入與卸載會造成不樂見 的延遲。Our U.S. Patent No. 6,956,223 describes an ion implanter of the above general design. A single wafer is held in a movable substrate holder. While the ion beam can be manipulated, the implanter is operated such that the ion beam follows a fixed path during implantation. Conversely, the wafer holder moves along the two orthogonal axes such that the ion beam scans over the wafer following the grating pattern. The above design is particularly suitable for continuous wafer processing where the handling device must unload the processed wafer prior to loading the new wafer to be implanted. Loading and unloading wafers between each implant can cause unpleasant delays.

我們的美國專利US6,555,825係描述一種如第1圖所 示之具有雙掃瞄臂的離子植入機。每一掃瞄臂具有一機動 化轂單元A,其可以繞著軸XI在掃瞄位置(顯示於右方) 與載入位置(顯示於左方)之間旋轉。 一中空臂B係在其一端可旋轉地裝設至轂單元,而可 以繞著軸X2轉動以經由離子束進行晶圓掃瞄。臂之另一 端設置有一晶圓固持器C。晶圓固持器C可以繞著軸X3 旋轉,以改變晶圓的方位。 6 1374484Our U.S. Patent No. 6,555,825 describes an ion implanter having a dual scanning arm as shown in Figure 1. Each of the scanning arms has a motorized hub unit A that is rotatable about an axis XI between a scanning position (shown to the right) and a loading position (shown to the left). A hollow arm B is rotatably mounted to the hub unit at one end thereof and is rotatable about the axis X2 for wafer scanning via the ion beam. The other end of the arm is provided with a wafer holder C. Wafer holder C can be rotated about axis X3 to change the orientation of the wafer. 6 1374484

每一掃瞄臂之結構與配置係使得當掃瞄臂位於載 置時,掃瞄臂位在軸XI上方且因而位在離子束D之 上方。這是很重要的,因為晶圓固持器可以被載入與甸 而不會因為離子束存在而有任何不希望的效應。在此 轂單元可以被旋轉90°以輸送晶圓固持器至掃瞄位置 中在該掃瞄位置處晶圓係通過離子束路徑而被掃瞄。 線所示,晶圓可以在臂上從位置 P1經由下方位置向 動至位置P2。在此離子植入機中,使用帶狀離子束以 此移動可以看見整個被植入的晶圓。 設置兩個這樣的掃瞄臂係使得一掃瞄臂可以用來 一晶圓,同時另一掃瞄臂可以被定位成用於同時的晶 入與卸載。因此,一旦一晶圓完成了植入,另一晶圓 一掃瞄臂上即準備好進行植入。這樣的掃瞄臂配置無 生線性的光栅掃瞄。 這樣的徑向掃瞄配置之另一缺失即是最終的非均 量特性,非均勻劑量特性是由橫越晶圓寬度之掃瞄速 差異所產生"這是因為晶圓最靠近樞轉頭的邊緣係比 掃瞄更慢,造成了在晶圓之該側的較高劑量。 【發明内容】 為了解決發明背景敘及之問題,本發明在於一種 離子植入機令用以固持基材以於植入期間暴露於一離 之基材固持器組件,基材固持器組件包含:一基座, 以繞著一第一軸旋轉;以及至少兩支撐臂,其從該基 入位 路徑 '載, 時, ,其 如虛 下移 使得 掃睡 圓載 在另 法產 勻劑 度的 外緣 在一 子束 其可 座延 7 1374484 伸至設置有多個基材固持器之末端。基座之旋轉使得該些 基材固持器可以採用多個指定的位置,該至少兩支撐臂從 取代該旋轉軸的點處開始延伸實質上相等距離且分隔一實 質上相等的分離角度,從而以該分離角旋轉該基座時可使 得該些支撐臂在該些指定位置之間移動。The structure and configuration of each of the scanning arms is such that when the scanning arm is in position, the scanning arm is above the axis XI and thus above the ion beam D. This is important because the wafer holder can be loaded into the Dian without any undesired effects due to the presence of the ion beam. The hub unit can be rotated 90° to transport the wafer holder to the scanning position where the wafer is scanned through the ion beam path. As shown by the line, the wafer can be moved from position P1 to position P2 on the arm via the lower position. In this ion implanter, a strip of ion beam is used to move the entire implanted wafer. Two such scanning arm systems are provided such that one scanning arm can be used for one wafer while the other scanning arm can be positioned for simultaneous incorporation and unloading. Therefore, once a wafer has been implanted, the other wafer is ready for implantation on the scan arm. Such a scanning arm is configured with a linear raster scan. Another missing feature of such a radial scan configuration is the resulting non-uniformity characteristic, which is caused by the difference in scan speed across the width of the wafer. This is because the wafer is closest to the pivoting head. The edge is slower than the scan, resulting in a higher dose on that side of the wafer. SUMMARY OF THE INVENTION To solve the problems described in the background of the invention, the present invention resides in an ion implanter for holding a substrate for exposure to a substrate holder assembly during implantation, the substrate holder assembly comprising: a pedestal for rotating about a first axis; and at least two supporting arms, which are loaded from the base path, when they are moved downwards so that the sweeping circle is loaded outside the other method The rim has a sub-bundle that can be extended 7 1374484 to the end where a plurality of substrate holders are disposed. The rotation of the pedestal allows the substrate holders to adopt a plurality of designated positions that extend from the point of replacing the axis of rotation by a substantially equal distance and are separated by a substantially equal separation angle, thereby The separation angle rotates the base to move the support arms between the designated positions.

因此,可以提供兩個或更多個範例性固持器,以被旋 轉而替換位置。例如,一位置可以對應於一基材掃瞎位置, 且另一位置可以對應於一基材載入/卸載位置。接著,基材 固持器組件可以包含一對支撐臂,其設置在基座之旋轉轴 的相對側。當基座在指定的位置之間旋轉時,一支撐臂從 掃瞄位置移動至載入位置,並且另一支撐臂從載入位置移 動至掃瞄位置。Thus, two or more exemplary retainers can be provided to be rotated to replace the position. For example, one location may correspond to a substrate broom location and another location may correspond to a substrate loading/unloading location. Next, the substrate holder assembly can include a pair of support arms disposed on opposite sides of the axis of rotation of the base. As the base rotates between the designated positions, one support arm moves from the scanning position to the loading position and the other support arm moves from the loading position to the scanning position.

可以使用超過兩個支撐臂。例如,可以使用三個支撐 臂(其被配置成分離1 20° )或四個支撐臂(其被配置成分 離 9 0 ° )。明顯地,設置三個支撐臂提供了三個指定的位 置,並且同樣地,四個支撐臂提供了四個指定的位置。在 每一指定的位置可以執行各種製程(例如將基材卸載、將 基材載入、將基材卸載及載入、植入、清潔、蝕刻、退火、 沉積等等)、此一或多個指定的位置可以不具有聯合的製 程,亦即基材可以僅停置在此位置,而其他基材係在一或 多個其他指定位置處被處理。 較佳地,每一基材固持器具有一支撐表面以支撐基材 使其實質上正交於支撐臂之縱向轴,並且該至少兩支撐臂 可以繞著其縱向軸旋轉。可選地,支撐表面可以繞著其中 8 1374484More than two support arms can be used. For example, three support arms (configured to separate 1 20°) or four support arms (which are configured to separate from 90 °) can be used. Obviously, the provision of three support arms provides three designated positions, and as such, four support arms provide four designated positions. Various processes can be performed at each specified location (eg, unloading the substrate, loading the substrate, unloading and loading the substrate, implanting, cleaning, etching, annealing, depositing, etc.), one or more The specified location may not have a combined process, i.e., the substrate may only be parked at this location, while other substrates are processed at one or more other designated locations. Preferably, each substrate holder has a support surface to support the substrate substantially orthogonal to the longitudinal axis of the support arm and the at least two support arms are rotatable about its longitudinal axis. Alternatively, the support surface can be wrapped around 8 1374484

心軸旋轉。這樣可以改變被基材固持器所固持住之基材 方位。 較佳地,該至少兩支撐臂可以沿著其縱向軸移動, 而可以改變每一基材固持器與該基座相隔之距離。這使 基材可以被移動進出一束,並且在此方向通過離子束被 瞄。 本發明也在於一種離子植入機,其包含:一離子源 一光學裝置,其可操作以導引由該離子源產生的多個離 沿著一離子束路徑行進至一製程腔室以植入到基材中; 基材傳送機構;以及如上述之基材固持器組件,可以固 基材於該製程腔室中。該至少兩支撐臂係實質上正交於 子束路徑而延伸。一第一指定位置係對應於面向離子束 基材固持器。一第二指定位置係對應於在離子束路徑之 且與該基材傳送機構合作之基材固持器,藉此使得基材 以被置放在該基材固持器上且從該基材固持器移除。 較佳地,該至少兩支撐臂可以沿著其縱向軸移動, 而可以改變每一基材固持器與該基座相隔之距離。可 地,該基座可以具有一聯合的掃瞄單元,其可操作以沿 其縱向軸往復地掃瞄該支撐臂。此外,該掃瞄單元可操β 以在實質上正交於該支撐臂之縱向軸及離子束路徑兩者 方向上掃瞄該支撐臂。這允許基材相對於一固定的離子 被掃瞄,例如根據一光栅圖案。替代性地,基材可以被 持住且同時一離子束係被掃瞄橫越基材,或可以使用基 與離子束皆被移動之混合系統。 的 從 得 掃 I 子 持 離 之 外 可 從 選 著 的 束 固 材 9 1374484The spindle rotates. This changes the orientation of the substrate held by the substrate holder. Preferably, the at least two support arms are movable along their longitudinal axes, and the distance between each substrate holder and the base can be varied. This allows the substrate to be moved in and out of the beam and directed through the ion beam in this direction. The invention also resides in an ion implanter comprising: an ion source-optical device operative to direct a plurality of ions generated by the ion source to travel along a path of an ion beam to a processing chamber for implantation Into the substrate; a substrate transfer mechanism; and a substrate holder assembly as described above, which can be fixed in the process chamber. The at least two support arms extend substantially orthogonal to the beam path. A first designated location corresponds to the ion beam oriented substrate holder. a second designated location corresponds to a substrate holder in the ion beam path and cooperating with the substrate transport mechanism, thereby causing the substrate to be placed on the substrate holder and from the substrate holder Remove. Preferably, the at least two support arms are movable along their longitudinal axes, and the distance between each substrate holder and the base can be varied. Alternatively, the base can have a combined scanning unit operable to reciprocally scan the support arm along its longitudinal axis. Additionally, the scanning unit can be operative to scan the support arm in a direction substantially orthogonal to both the longitudinal axis of the support arm and the ion beam path. This allows the substrate to be scanned relative to a fixed ion, for example according to a grating pattern. Alternatively, the substrate can be held while an ion beam is scanned across the substrate, or a hybrid system in which both the base and the ion beam are moved can be used.

It can be understood that Fig. 2 is only an application example of the present invention and does not. Figure 2 shows an ion implanter 10 known for implanting ions into a semiconductor. The ion system is generated by ion source 14 and follows an ion path 34, wherein the ion path 34 is hereby passed through a mass analysis platform 30. The desired mass of ions is passed through a mass resolution slit 32, and then impacts the semiconductor wafer. The ion implanter 10 includes an ion source 14 to produce a desired ion beam, and the ion source 14 is evacuated by the pump 24. Within a vacuum f. The ion source 14 generally includes an arc chamber 16 having a cathode 20 disposed at one end thereof. The ion source 14 can be operated with an anode provided by the wall 18 of the arc chamber 16. The cathode 20 is heated to generate a plurality of hot electrons. The hot electrons emitted by the cathode 20 are attracted to the anode (the chamber wall 18 in the vicinity). The gas molecules are ionized as the gas molecules traverse the arc chamber 16, thereby forming a plasma and generating a genomic. The path followed by the hot electrons can be controlled to avoid electrons having only the shortest path of the chamber wall 18. A magnet assembly 46 provides a magnetic field that extends the arc chamber 16 such that the hot electrons follow a spiral path along the length of the arc chamber 16 to the cathode 44, wherein the opposing projections, although forming the wafer 12 The extraction of the empty chamber 15 t 16 of the 12 ° species is sufficient in the case of the extraction, and the thermoelectricity is followed by the passage of the electrical energy toward the & 44 position 10 1374484 in the arc chamber 16 At the end.

The arc chamber 16 is maintained at a low pressure within the vacuum chamber 15. The hot electrons traveling through the arc chamber 16 ionize the gas molecules within the arc chamber 16, and can also rupture the molecules. The ions established in the plasma, which may contain a mixture of ions, will also contain traces of contaminant ions (e.g., contaminant ions from the material of the chamber wall 18).

The power supply 21 applies a potential difference between the ion source 14 and the subsequent mass analysis platform 30 to accelerate the extracted ions, and the ion source 14 and the mass analysis platform 30 are insulated from each other by an insulator (not shown). Geoelectric isolation. Next, the mixture of extracted ions passes through the mass analysis platform 30 such that the ions travel around a curved path under the influence of the magnetic field. The radius of the curved path through which any ion travels is determined by the mass of the ion, the state of charge, and the energy, and the magnetic field 41 is controlled so that for a set of ion energies, only the desired mass to charge ratio and energy ions will It exits along a path that conforms to the mass resolution slit 32. The exposed ion beam is then delivered to a target (ie, the substrate wafer 12 to be implanted, or one of the bundles 38 when there is no wafer 1 2 at the target location) Process chamber 40. In other modes, the beam can also be accelerated or decelerated using a lens assembly that is positioned between the mass analysis platform 30 and the wafer position. 11 1374484 The semiconductor wafer 1 2 is mounted on a wafer holder 36 which is transferred into and out of the wafer holder 36, for example, via a load lock chamber (not shown). The ion implanter 10 operates under the management of a controller, such as a suitably programmed computer 50. The computer 5 controls the scanning of the wafer 12 through the ion beam 34 to achieve the desired scanning pattern. These scan patterns can include raster scans (including staggered patterns as are known in the art).

第3圖顯示用以固持兩個晶圓l〇2a、b於如同第2圖 之離子植入機10内的設備100。第4圖顯示設置在製程腔 室40内之設備100,其截面圖係對應於離子束34平面稍 微上方的戴面。如同將可以瞭解的是,設備1〇〇裝設至製 程腔室40之壁130,而離子束34係被掃瞄或將晶圓i〇2a、 b通過離子束34來掃瞄。在晶圓102a、b之載入與卸載期 間’設備100也與一操控裝置132合作。Figure 3 shows the apparatus 100 for holding two wafers 1a, 2b, as in the ion implanter 10 of Figure 2. Figure 4 shows the apparatus 100 disposed within the process chamber 40, the cross-sectional view of which corresponds to the wear surface slightly above the plane of the ion beam 34. As will be appreciated, the device 1 is mounted to the wall 130 of the process chamber 40, and the ion beam 34 is scanned or scanned by the ion beam 34 by the wafers i〇2a, b. The device 100 also cooperates with a steering device 132 during loading and unloading of the wafers 102a, b.

設備100包含一與旋轉致動器134配合之旋轉台 B6,其中該旋轉致動器134可以提供旋轉台1〇6在箭頭 110所指方向之全範圍旋轉。旋轉台106係被一交又滾子 軸承(crossed-roller bearing)所支撐,並且密封係由具有 微分唧筒抽吸(differential pumping)的浮動空氣轴承迷 宮密封單元(floating air bearing labyrinth seal unit)所 提供。旋轉致動器134具有一聯合的凸緣以將此設備裝設 至製程腔室4〇。 兩個掃瞄臂lMa、b被提供,每一掃瞄臂114a、b在 其末端具有一晶圓固持器 H6a、b。每一掃瞄臂114a' b η 1374484Apparatus 100 includes a rotary table B6 that cooperates with a rotary actuator 134 that provides rotation of the rotary table 1〇6 in the full range of directions indicated by arrow 110. The rotary table 106 is supported by a crossed-roller bearing, and the seal is provided by a floating air bearing labyrinth seal unit having differential pumping (differential pumping) . The rotary actuator 134 has a combined flange to mount the apparatus to the process chamber 4''. Two scanning arms lMa, b are provided, and each of the scanning arms 114a, b has a wafer holder H6a, b at its end. Each scanning arm 114a' b η 1374484

從晶圓固持器116a、b向後朝著支撐旋轉台106延伸,並 且實際上延伸穿過旋轉台106而被一線性致動器118a、b 接受,其中該線性致動器118a、b設置在旋轉台106的後 部。掃瞄臂114a、b藉由密封的軸襯120a、b被支撐在旋 轉台106處,其中該轴襯120a、b使得掃瞄臂114a、b藉 由線性致動器118a、b透過旋轉台106被驅動。依此方式, 晶圓固持器1 1 6 a、b隔開旋轉台1 0 6的距離可以改變,即 晶圓102a、b可以在箭頭122所指方向被驅動進出製程腔 室。 除了驅勤掃瞄臂114a、b進出製程腔室40之外,線性 致動器118a、b也驅動掃瞄臂114a、b的旋轉運動,從而 使掃瞄臂114a'b繞著其縱向軸旋轉(如箭頭124所示)。Extending from the wafer holders 116a, b rearwardly toward the support rotary table 106, and actually extending through the rotary table 106 and being received by a linear actuator 118a, b, wherein the linear actuators 118a, b are disposed in rotation The rear of the station 106. The scanning arms 114a, b are supported at the rotary table 106 by sealed bushings 120a, b which cause the scanning arms 114a, b to pass through the rotary table 106 by linear actuators 118a, b driven. In this manner, the distance between the wafer holders 1 1 6 a, b spaced apart from the rotating stage 106 can be varied, i.e., the wafers 102a, b can be driven into and out of the process chamber in the direction indicated by arrow 122. In addition to the drive scan arms 114a, b entering and exiting the process chamber 40, the linear actuators 118a, b also drive the rotational movement of the scan arms 114a, b, thereby rotating the scan arm 114a'b about its longitudinal axis. (As indicated by arrow 124).

每一掃瞄臂1 1 4 a、b為空心,因而可以提供對於晶圓 固持器1 1 6a、b的維護配線。這包括了一驅動機構,其使 得支撐晶圓l〇2a、b之夾盤126a、b可以繞著其中心旋轉, 如箭頭128所示。夾盤126a、b係靜電地固持住晶圓102a、 b,使得失盤126a、b之旋轉引起晶圓102a、b之對應旋轉。 其他裝設晶圓1 〇2a、b至夾盤126a、b的方法也同樣可行。 第3和4圖顯示具有旋轉台106組之設備100,因此 晶圓固執鍵1 1 6 a佔據了載入位置,而晶圓固持器1 1 6 b佔 據了掃瞄位置。將旋轉台106旋轉180°可以替換被晶圓固 持器I 1 6a、b所佔據的位置。 在載入位置,掃瞄臂114a繞著方向124旋轉以確保晶 圓102a向上地面對。將晶圓102a固持至夾盤126a之靜電 13 1374484Each of the scanning arms 1 1 4 a, b is hollow so that maintenance wiring for the wafer holders 1 16a, b can be provided. This includes a drive mechanism that causes the chucks 126a, b supporting the wafers 102a, b to rotate about their center, as indicated by arrow 128. The chucks 126a, b electrostatically hold the wafers 102a, b such that rotation of the wafers 126a, b causes corresponding rotation of the wafers 102a, b. Other methods of mounting the wafers 1 〇 2a, b to the chucks 126a, b are equally feasible. Figures 3 and 4 show the device 100 with the rotating table 106 set so that the wafer stub 1 1 6 a occupies the loading position and the wafer holder 1 16 b occupies the scanning position. Rotating the rotary table 106 by 180° can replace the position occupied by the wafer holders I 1 6a, b. In the loading position, the scanning arm 114a rotates about the direction 124 to ensure that the wafer 102a is facing up. Electrostatic holding wafer 102a to chuck 126a 13 1374484

力可以中斷,並且操控裝置132將晶圓102a從夾盤126a 移除。第4圖係顯示一簡單的操控裝置132,其包含一對 鉸接顎136,鉸接顎136可以藉由凸輪138之旋轉而開啟 及閉合。顎136與凸輪138在一裝設至柄142之臂140上 懸空。柄142係允許垂直移動(即進出紙面),以及如箭頭 144所示之旋轉。是以,操控裝置132可以旋轉成使得顎 136在晶圓102a上方移動,顎136在柄142上可以下降且 閉合以抓持晶圓l〇2a。接著,操控裝置132在柄142上上 升,並且接續地繞著方向144旋轉,從而使顎136中之晶 圓102a經由閘閥146搖盪出製程腔室40。由於真空考量, 真空閉鎖室較佳地鄰近第4圖所示之單閘閥1 4 6。然後, 逆向程序可以用來將一新晶圓 102a載入到晶圓固持器 126a上。如同熟習此技術領域之人士將可以瞭解的,可以 使用許多其他替代的操控裝置配置,以將晶圓載入及卸載。The force can be interrupted and the handling device 132 removes the wafer 102a from the chuck 126a. Figure 4 shows a simple handling device 132 that includes a pair of hinges 136 that can be opened and closed by rotation of the cam 138. The cymbal 136 and the cam 138 are suspended from an arm 140 attached to the handle 142. The shank 142 allows vertical movement (i.e., in and out of the paper) and rotation as indicated by arrow 144. Thus, the steering device 132 can be rotated such that the crucible 136 moves over the wafer 102a and the crucible 136 can be lowered and closed on the handle 142 to grip the wafer 10a. Next, the steering device 132 is raised above the shank 142 and continues to rotate about the direction 144 such that the wafer 102a in the crucible 136 is shaken out of the process chamber 40 via the gate valve 146. Due to vacuum considerations, the vacuum lock chamber is preferably adjacent to the single gate valve 146 shown in FIG. The reverse process can then be used to load a new wafer 102a onto the wafer holder 126a. As will be appreciated by those skilled in the art, many other alternative steering arrangements can be used to load and unload wafers.

一旦將新晶圓102a載入至夾盤126a上且被靜電力固 持住後,掃瞄臂1 1 4即準備好可以旋轉。如第3圖所示, 載入位置可以看到晶圓1 0 2 a被固持成隔開離子束路徑3 4 一段距離。掃瞄臂114a將晶圓102a固持在離子束路徑34 高度的上方,並且掃瞄臂114a也沿著方向122朝著旋轉台 106縮回,藉此將晶圓102a從離子束路徑34向後移動。 在掃瞄位置,掃瞄臂1 1 4b沿著方向1 22延伸遠離旋轉 台106且繞著方向124旋轉,從而使晶圓102b被挺直地固 持住以面對來臨的離子束 34。在一些應用中,離子束 34 較佳地係以一角度(而非垂直地)撞擊晶圓1 0 2 b,例如當 14 1374484Once the new wafer 102a is loaded onto the chuck 126a and held in place by electrostatic force, the scan arm 1 14 is ready to rotate. As shown in Fig. 3, the loading position can be seen that the wafer 10 2 a is held to be separated by a distance from the ion beam path 34. The scan arm 114a holds the wafer 102a above the height of the ion beam path 34, and the scan arm 114a is also retracted toward the turntable 106 along the direction 122, thereby moving the wafer 102a rearward from the ion beam path 34. In the scanning position, the scanning arm 1 14b extends away from the rotating table 106 in direction 1 22 and rotates about direction 124 such that wafer 102b is held upright to face the incoming ion beam 34. In some applications, ion beam 34 preferably strikes wafer 1 0 2 b at an angle other than vertical, such as when 14 1374484

Rotate to achieve the position of the Greek. In this manner, the features on wafer 102b (eg, accurately aligned with the ion beam. In this embodiment, wafer 1 0 2 b is held in scan ribbon beam 34 is scanned across quiescent The wafer 102b is also possible. For example, the ribbon cat is scanned across the wafer 102b without using a ribbon beam, such as a grating pattern. In addition to the beam 34 scanning, the wafer 102b can be scanned. The actuator 118a drives the scanning arm 114 in the X direction (reciprocating movement in the entanglement, and can be easily scanned in the X direction. In order to move the wafer holders 116a, b to the loading chamber, three must be performed. Movement: (1) The rotating table must be around 180°, if necessary, it can be clockwise or counterclockwise; (2) the sweep must be rotated 90° around the direction 124, and the scanning arm 114a is the scanning arm 1 1 4 b The clock direction; and (3) the scanning arm moves along the direction 1 22, the scanning arm 1 14a is away from the rotating table chamber 40 and the scanning arm 114b is moved toward the rotating table 106. These movements can be realized by the controller 50. But sweeping the three different mobile systems to prioritize the order. It is beneficial to show these moves to avoid The capacity of the wafer ion implanter 10 is maximized. The scan arm 114a is in. This can be transferred to make the wafer. In addition, the missing wafer 102b trench wall can be positioned while, however, Other matching beams can be used, except that the ions are linearized: < is horizontal) and the scanning position is 1 1 0. The aiming arm 11 4 a, b is counterclockwise and 1 1 4 a, b must be 1 0 6 and enter the brake. Roughly, how does the controller 50, at the same time, enter 102a, b is separated by the b-series 15 1374484

It will be appreciated by those skilled in the art that variations of the above-described embodiments can be made without departing from the scope of the invention. For example, the above embodiments illustrate the invention for implanting a semiconductor wafer. However, the invention has broader applicability. For example, the invention can be used in any type of ion implanter, whether it is an ion implanter for a semiconductor wafer or any other type of substrate. Moreover, the invention can be used in any other type of apparatus that requires manipulation of the workpiece where the workpiece is rotated between a number of designated locations. The above embodiment describes a dual scan arm device 100. However, three or more scanning arms 1 1 4 a, b are used. Advantageously, the scanning arm b is equidistant from the center of rotation of the rotary table such that the same position is used when the wafer is moved between a plurality of positions. Advantageously, the scanning arms 1 14 a, b are separated by substantially equal angles such that the aiming arms 1 14 a, b rotate only between a plurality of consecutive positions. Each bit corresponds to a station where a processing step (e.g., implant/unload, etch, anneal, deposit, clean, etc.) is performed at the station. Loading and can be split into two separate actions performed at different stations, wafer 102a, b or other substrate before a new wafer 102a, b or other next station is loaded The station was uninstalled. One or more locations are idle locations at which the wafer 1 〇 2a, b or substrate is parked before moving to the next station. An idle station is a circle of useful space away from the field, this implant, the inside, can be 4a, outside the holder, can be swept into the 'unloading one substrate can be other, 16 1374484 in between The limited space at the station excludes the installation of processing equipment adjacent to this location.

上述之本發明實施例具有許多移動程度,以提供一彈 性的系統。然而,設備100不需要有這樣的能力。例如, 設備100僅繞著方向110旋轉,以使得掃瞄臂114a、b可 以替換位置。設置操控裝置必須可以適於將晶圓1 〇2a、b 從一垂直方位載入及卸載,但是這樣的應用是直接的。掃 瞄臂114a、b不需要在方向122(即朝著及遠離旋轉台106) 為可動,這是因為晶圓l〇2a、b可以在離子束34之外而旋 轉。 雖然第3圖顯示出掃瞄臂1 1 4 a、b係延伸穿過旋轉台 106,可以提供可伸縮臂,其不需要穿透旋轉台106。 【圖式簡單說明】 為了詳加瞭解本發明,一較佳實施例係參照附圖而被 敘述,其中: # 第1圖為根據習知技術之一雙掃瞄臂設備的立體圖。 第2圖為一傳統之離子植入機的示意圖。 第3圖為根據本發明實施例之一基材固持器組件的立 體圖。 第4圖為包含第3圖基材固持器組件之製程腔室的截 面圖。 【主要元件符號說明】 17 1374484The embodiments of the invention described above have a number of degrees of movement to provide a resilient system. However, device 100 does not need to have such capabilities. For example, device 100 only rotates about direction 110 such that scan arms 114a, b can replace positions. The setting controls must be adapted to load and unload the wafers 1 〇 2a, b from a vertical orientation, but such applications are straightforward. The scanning arms 114a, b need not be movable in the direction 122 (i.e., toward and away from the rotating table 106) because the wafers 102a, b can be rotated outside of the ion beam 34. Although FIG. 3 shows that the scanning arm 1 1 4 a, b extends through the rotary table 106, a telescopic arm can be provided that does not need to penetrate the rotary table 106.
